2022 Aston Martin Valkyrie Spider

RA

6.5L V12 Hybrid

A naturally aspirated 6.5-litre V12 spinning past 11,000 rpm, backed by a battery-fed electric motor that fills the torque gaps. It is the loudest, highest-revving engine fitted to a road car in the modern era.

Built by Cosworth to an Adrian Newey brief, it was engineered as a stressed chassis member — the gearbox and rear suspension bolt straight to it, exactly as on a Formula 1 car.

• It revs beyond 11,000 rpm, higher than any other production road-car engine.
• The V12 is a stressed member: it carries suspension loads instead of sitting in a subframe.
• An electric motor fills in low-rev torque so the engine can be tuned purely for top-end power.
